Na et al reported the High-Flexion Knee Score (HFKS) for evaluating a patient who has had a total knee arthroplasty (total knee joint replacement). The score eliminates the ceiling effect seen with other scoring instruments. The authors are from Samsung Medical Center and Sungkyunkwan University in Korea.
Parameters (2 pain and 7 functional measures during high-flexion knee maneuvers):
(1) pain on ascending or descending stairs
(2) pain while sitting on or rising from the floor
(3) difficulty ascending stairs
(4) difficulty descending stairs
(5) difficulting sitting on or rising from the floor
(6) difficulty sitting on or rising from a low chair
(7) difficulty with cross-legged sitting
(8) difficulty squatting
(9) difficulty kneeling

total score =
= SUM(points for all 9 measures)
Interpretation:
• minimum score: 9
• maximum score: 45
• The higher the score the better the knee function.
Purpose: To evaluate a patient following a total knee arthroplasty using the high-flexion knee score (HFKS) of Na et al.
